Answer :
The blood will flow through the given structure in the following order:
Systemic veins, right atrium, right ventricle, pulmonary arteries, pulmonary veins, left atrium.
Explanation:
The flow of blood in the heart is as follows:
- The systemic veins bring the deoxygenated blood from the body to the right atrium of the heart.
- From the right atrium the blood flows into right ventricle through the tricuspid valve.
- The blood then moves into the right ventricle from where it is pumped into the pulmonary arteries that take the blood to the lungs.
- After the blood loads with oxygen in the lungs the pulmonary vein takes up the blood and pumps it into the left atrium through pulmonary valve.
- Next, the blood moves into the right ventricle.
- From the left ventricle it is pumped into the main systemic artery or the aorta.
